Working Magnetic Motor on you tube??

@ken_nyus

The RPM is controlled by a tiny motor from a constant voltage source so it's not very accurate. I do know from my homopolar disk tests that it will spin up to about 11,000 RPM.
I never tried running this up that fast and never calculated how fast the magnets would be going at 11,000 RPM but the thought of one flying out and hitting the back of your hand or some other bony part (I can't even think eyes) would probably leave a mark!

I have a new IR tach coming and should be here Friday. (cause I do calculations all day at work so I try to avoid them at home)

It will keep the AGW lock down to about 200-300 RPM. As it spins faster the waveform reduces in size as expected but way less than I thought would be the case.
In the video I would guess about 800-1000 on the rotor but wait for the IR tachometer.

Several of us got this sub rev tacho meters that is giving a timestamp 720 times or more per rev. If we could get a sub rev tacho on the stator and then use an index mark on the rotor, we should be able to find the exact position of the stator when it is running in the AGW locking. Then we will see the acceleration part and the braking, and later if we help the rotor up in speed until we losses the grip, we can see how it was lost, and then modify the rotor or stator for a better match.


Yes, I know I should do it. I have all the equipment and the rotor -stator that lock in AGW direction, but I am swamped in work at the moment an hardly got time to follow this development, so until I get more time, I hope someone will look into this.

hi lumen and everybody

I'm a now studying for my masters degree in physics, and although everything I've learned says this can't work, I'm feeling optimistic. i have been following the developments over the last week, and i think what you have done, lumen, can be very enlightening. but i have some remarks.

i don't know how your tachometer is built, but I'm assuming it contains an electromagnet and a diode bridge rectifier. if it is so, the picture your are seeing does not indicate what you think. you would expect the same (or almost the same) signal from a magnet spinning in a constant speed.

so, from what we see on the scope, we can say that for every two "hills", the stator magnet makes a turn. so we can calculate its rotation frequency from that. it would be interesting to see the main rotor frequency as well, it might not be what we expect, in relation to the stator frequency.

i think a good way to look at it, is to look at the gaps between the magnets on the main rotor, instead of the magnets themselves. we can clearly define a "north" gap (a gap to whom the magnets on both sides point their north pole) and a "south" gap. now it is clear that the south part of the stator magnet is attracted to the north gap, and so on.

it might be interesting to try to connect the stator magnet to the main rotor with two gear wheels, so that it would turn in the frequency we set, and trying to give a different phase each time to the stator magnet in relation to the main rotor.

Congratulations on the good work so far! keep posting to keep us up to date.

Rather than using gears, maybe better to drive the Rotor and Stator with Stepper motors to adjust the phase relationship between them?

To try understand why there may be acceleration, please look at the principal discovered by the researchers of Inductrack.
https://www.llnl.gov/str/Post.html
http://en.wikipedia.org/wiki/Inductrack

Once a certain speed has been exceeded the drag coefficient reduces significantly. In the case of Inductrack something like 200:1.

With the rotor being spun AGW, as long as it exceeds the threshold speed the drag would reduce in a non linear way and so would be expected to accelerate.

The same may happen if spun GW fast enough

anyway just something i remembered from awhile back. Might help, might be totally BS in this case

In all attempts of creating a pm motor I have seen up to now there is either the attempt to trigger it by an electic impulse or mechanically hiding a part.
When I saw this thing one thing came back to my mind. Most of you have seen it and came to the conclusion that this is nonsense
like this (sorry couldn?t find the video): http://keelynet.com/gravity/hamag.htm (just ignore the paranormal bull**** on the site)

Of course it only works because the hand is not fixed but exactly this is the trick. Know what I mean?
